I am replacing an existing firewall with a new NSA sonicwall for a client.
The client has remote users that connect remotely to the office via dial-in VPN. The existing firewall requires the client to install a local certificate to authenticate the connection. I am not sure how to re-create this environment on the Sonicwall. I imported the RootCA certificate from the clients internal CA, but the Sonicwall is not letting me choose it in the SSL VPN settings.
I will need pretty detailed instructions as I am not strong with SSL and certificates. Is this even possible? If not, what is the recommended way - just a signed CA cert using public key encryption?
Thanks for your time.
